When the blood pressure in a capillary exceeds the osmotic pressure in the capillary what is the net movement of fluid?
The movement should be OUTWARD toward the interstitial fluid. This is because the blood pressure is greater than the osmotic pressure (or more correctly the onconic/colloid pressure, since the membrane is actually quite permeable to ions but is not permeable to plasma proteins), and thus fluid (water and ions, along with other small molecules) can flow OUT of the capillary bed.

When the osmotic pressure in a capillary exceeds the blood pressure in the capillary what is the net movement of fluid?
water and waste will move in capillary . water and waste will move in capillary .
Filtration results when substances are forced through capillary walls by osmotic pressure?
Filtration results when nutrients are moved through the capillary walls by hydrostatic pressure. Hydrostatic pressure in the capillaries is greater than the osmotic pressure so there is a net movement of fluid and/or solutes out of the capillaries.
How do net hydrostatic pressure and net osmotic pressure each change along the length of a capillary?
Net hydrostatic pressure decreases along the length of a capillary due to resistance and filtration of fluid out of the capillary. In contrast, net osmotic pressure remains relatively constant along the capillary length, as proteins and solutes that contribute to osmotic pressure do not leave the capillary as easily.
Which net pressure draws fluid into the capillary?
net osmotic pressure
What reflects balance between the direction and amount of fluid that flows across capillary walls?
Hydrostatic and osmotic pressure.
The most important force driving reabsorption at the venous end of a capillary is?
Blood colloid osmotic pressure
What aids the passage of water into the blood on the venous side of the capillary?
osmotic pressure
Why water and dissolved substances leave the arterioles end of the capillary and enter the venule end?
Water and dissolved substances leave the arteriole end of the capillary due to hydrostatic pressure being higher than osmotic pressure and enter the venule of the capillary due to osmotic pressure being higher than hydrostatic pressure.
Which forces act to move fluid back into the capillary reabsorption?
Osmotic pressure is what draws fluid back into the capillary from the tissues.
Where does fluid reabsorb into the capillary?
Fluid reabsorbs into the capillary primarily at the venous end of the capillary bed. This process occurs due to the balance of hydrostatic and osmotic pressures; as blood pressure decreases along the capillary, the osmotic pressure from plasma proteins draws fluid back into the capillary. This reabsorption is crucial for maintaining blood volume and tissue fluid balance.
What are the results of when the blood pressure in the capillaries greatly exceeds the osmotic pressure of the blood?
we produce from the cappilarries
What is the Capillary fluid shift mechanism?
exchange of fluid that occurs across the capillary membrane between the blood and the interstitial fluid. This fluid movement is controlled by the capillary blood pressure, the interstitial fluid pressure and the colloid osmotic pressure of the plasma. Low blood pressure results in fluid moving from the interstitial space into the circulation helping to restore blood volume and blood pressure.
